Traveling between Milwaukee and Chicago is a routine trip for commuters, weekend visitors, and business travelers alike. Spanning roughly 90 miles across the state line, this Midwestern corridor connects two major lakeside hubs. Whether you need to catch a flight, get to a meeting, or plan a weekend getaway, you'll find that transit options are fast, frequent, and straightforward.
The fastest way to make the trip is the Amtrak Hiawatha train, which takes about an hour and a half. Driving via Interstate 94 is just as common, though your exact travel time will depend heavily on traffic congestion around the Illinois-Wisconsin border and entering downtown Chicago. Buses and airport shuttles offer budget-friendly alternatives if you don't want to drive or pay for parking.
Driving the Route via Interstate 94
Driving offers total flexibility, letting you set your own schedule and bring luggage or gear without restrictions. The direct road distance is about 90 miles, primarily utilizing Interstate 94 East (the Tri-State Tollway and the Bishop Ryan Expressway).
Standard Route and Mileage
From downtown Milwaukee, you'll jump onto I-94 heading south toward Racine, Kenosha, and the Illinois border. The highway transitions into the Tri-State Tollway as you approach northern Illinois. From there, you'll continue south before merging onto I-90/I-94 east toward downtown Chicago. Under clear conditions, the drive takes about 1 hour and 45 minutes.

Tolls and Costs
Illinois and Wisconsin handle tolling differently, and you'll encounter electronic toll collection once you cross into Illinois. Cash is rarely accepted at mainline plazas anymore, so you'll want to plan ahead.
- Bring an active I-PASS or IPASS toll transponder to keep costs down and avoid paying video toll fees.
- Rental cars often include transponders, but you should check with your rental agency about daily activation fees.
- Keep a credit card handy if you need to pay online video tolls after the fact.
Traffic Bottlenecks and Timing
Traffic is the single biggest variable when driving between these cities. Avoid driving during peak weekday rush hours (7:00 AM to 9:00 AM and 4:00 PM to 6:30 PM) if you want to steer clear of heavy congestion around the Edens Expressway junction and downtown Chicago approaches. Construction projects pop up frequently during warmer months, so check real-time mapping tools before you leave your driveway.
Taking the Train: Amtrak Hiawatha
For most travelers, the Amtrak Hiawatha service is the gold standard for this corridor. It eliminates the stress of highway traffic, offers a reliable schedule, and drops you right in the heart of downtown Chicago.
Stations and Stops
The standard Hiawatha route runs several daily round trips between Milwaukee Intermodal Station and Chicago Union Station. Depending on the specific run, trains make a few intermediate stops:
- Milwaukee Intermodal Station (Downtown)
- Milwaukee Mitchell International Airport (MKA)
- Sturtevant, Wisconsin
- Glenview, Illinois
- Chicago Union Station
Schedule and Travel Time
The entire journey takes approximately 1 hour and 29 minutes. Trains run consistently throughout the day, making it easy to plan a day trip or an extended stay. Tickets are generally affordable, though booking a few days ahead secures your preferred departure time. Onboard amenities include free Wi-Fi, power outlets at your seat, and a quiet car option if you need to work or rest in peace.
Bus and Shuttle Alternatives
If train tickets are sold out or you're looking for the absolute lowest fare, intercity buses are a reliable backup.
Greyhound and FlixBus
Carriers like Greyhound and FlixBus operate direct routes between the Milwaukee Intermodal Station and the Chicago Bus Station. Travel time usually hovers around 1 hour and 35 minutes to 2 hours, depending on traffic conditions. Fares are often cheaper than train tickets, though schedules are less frequent.
Airport Connections
If you're flying out of O'Hare International Airport, Wisconsin Coach Lines operates airport express buses that run directly from the Milwaukee area to O'Hare terminals. This saves you from having to travel all the way into downtown Chicago just to catch a connecting flight.
What to Expect Upon Arrival in Chicago
Arriving in downtown Chicago gives you immediate access to the Chicago Transit Authority (CTA) subway and bus networks.
If you arrive by train at Union Station, you're within walking distance of the Loop, Willis Tower, and multiple CTA bus lines. You can easily connect to the brown, pink, orange, or purple elevated train lines via nearby stations. Purchase a Ventra card or use contactless smartphone payment directly at the turnstiles to hop onto trains and buses seamlessly.
Frequently Asked Questions
Is it cheaper to drive or take the train?
If you're traveling solo, the Amtrak train is often cheaper or comparable once you factor in Chicago parking rates, which can easily exceed forty dollars a day. If you're traveling with a family or group, driving becomes more cost-effective.
Can I bring my bicycle on the Amtrak Hiawatha?
Yes, standard bicycles are permitted on the Hiawatha service, but you must reserve a bike space in advance when booking your ticket. Some trains require you to load your bike into a designated baggage car yourself.
What is the best time of day to drive to avoid traffic?
Traveling mid-morning (between 10:00 AM and 2:00 PM) or late evening yields the smoothest drive. Avoid Friday afternoons heading south and Sunday afternoons heading north, as weekend getaway traffic peaks during these windows.
Do I need an exact ticket time for the Amtrak Hiawatha?
Amtrak Hiawatha tickets are usually tied to a specific train departure, so check your booking confirmation carefully. Always arrive at the station at least 20 minutes before departure to allow for boarding.
